How the database is doing

Charts, notices and tables for the app’s managed database: connection wait, connections in use against the limit, errors, response time and queries per second, as hour buckets (?hours=, up to 168) or day buckets (?days=, up to 730) — send one, not both. Also errors by SQLSTATE code over the same range (summing to the buckets’ error lines), the latest stuck-query reading, this month’s uptime, notices for anything wrong right now, and the incident log. Null means not measured, never zero. No query text or row data. Requires apps:read.
